This is such a beautiful thing. You're a wonderful soul. The other day I got food for a homeless guy and I felt so good seeing the smile on his face.
But I think it would be better if you don't take photos of them. I don't think these were consensual. Giving is good and sharing it on social media is good too, heck I encourage it because I believe it can cause a ripple effect but I'd like people to do more discreetly.
You could take photos of what you got them, etc.
In any case, what you do is beautiful. The world needs kindness.
I do hope you continue in your wonderful gesture
